You have to specify two RTP destinations (with different port numbers, 
for example).
Try something like
./ffmpeg -re -i /tmp/test.mpg -vcodec copy -an \
-f rtp rtp://127.0.0.1:10000 -i /tmp/test.mpg -vn \
-acodec copy -f rtp rtp://127.0.0.1:20000

If I remember well, for this to work you would have to fix the "-an" and 
"-vn" options handling (the "video only" and "audio only" state is 
currently not reset at the new input file). I should have a patch for 
this; I'll send it later.


Obviously, you will have to generate the SDP file by hand...
